This patchset adds a stress test for kprobes and a test for checking optimized probes. The two tests are being added based on the below discussion: https://lore.kernel.org/all/20230128101622.ce6f8e64d929e29d36b08b73@kernel.o... kprobe_opt_types.tc is modified as per the below review comments: https://lore.kernel.org/all/1682506809.uus6y0ir3i.naveen@linux.ibm.com/#t
Changelog:
v3:
* Add Acked-by for kprobe_insn_boundary.tc * Simplify test for optimized probe, as suggested by Masami * Add exit_unresolved to exit as unresolved in case no probe was optimized
v2:
* Add an explicit fork after enabling the events ( echo "forked" ) * Remove the extended test from multiple_kprobe_types.tc which adds multiple consecutive probes in a function and add it as a separate test case. * Add new test case which checks for optimized probes.
